i made the drive from pensacola back to bradenton today. and there is a problem with the car. im not sure if it is because the exhaust is too big (apexi gt spec on a stock ka) but it seems like the car misses frequently. there is a serious dead spot from 4k to redline, it seriously doesnt move from there. and it just feels weak in general. the ka has 115k miles, so i know its still pretty good. when i first bought the car it was very strong, but ever since i drove today it feels very weak. and makes ZERO power after 4 grand. also, its running rich as hell. i didnt use the a/c, and just coming back to bradenton i had to fill up 5 times. and the entire back of my car is all black from smoke. the ka is stock, with a drop in filter, the exhaust, and a walbro fuel pump. so i need some help. i disabled the egr a while back, so maybe thats why its running like shit. im not sure, but its weak. not too sure if it could keep up with a civic ex. so i could use some help.
